What state is put in Box 17 of Form 1099 if no state withholding?

I would leave it blank based on this from the instructions

Boxes 16–18. State Information

These boxes may be used by payers who participate in the Combined Federal/State Filing Program and/or who are required to file paper copies of this form with a state tax department. See Pub. 1220 for more information regarding the Combined Federal/State Filing Program. They are provided for your convenience only and need not be completed for the IRS. Use the state information boxes to report payments for up to two states. Keep the information for each state separated by the dash line. If you withheld state income tax on this payment, you may enter it in box 16. In box 17, enter the abbreviated name of the state and the payer's state identification number. The state number is the payer's identification number assigned by the individual state. In box 18, you may enter the amount of the state payment.

If a state tax department requires that you send them a paper copy of this form, use Copy 1 to provide information to the state tax department. Give Copy 2 to the recipient for use in filing the recipient's state income tax return.

How do I get box 17 to pre-fill on my 1099 Misc since it is mandatory in Wisconsin 

Thanks for joining this thread, @Lynndr1.

I can share some insights about pre-filling the box 17 for the 1099 Misc form for Wisconsin.

The state of Wisconsin requires the filers to fill out the box 17 with the payer's state identification number. Just a heads up that you'll be charged $10 for each 1099 form that has missing information in boxes 16 and 17.

Here's how to get the box 17 to pre-fill:

1. Click Vendor.
2. Choose Print/E-file 1099s.
3. Select 1099 Wizard.
4. Click Get Started.
5. Select the vendors.
6. Click Continue.
7. On the Verify your 1099 info, make sure to fill out the State & Payer's State No. field. 
   This is the sample format: WI 999999999999999 (Wisconsin (WI) and your 15 digit WI withholding ID). 
8. Continue the prompts in running the 1099 wizard.

You can also contact the Wisconsin Department of Revenue if you have concerns about your Withholding ID number.

That should keep you going today, Lynndr1. Let me know if you have additional payroll questions. I'm still here to help you further. Have a good one!

I've tried this many times and it does not work.  Even when it's filled out on the verify information screen it still does not print on the forms and that information cannot be saved.

Let me help you add an info in Box 17 of the 1099 form, WSFOX.

You need to make sure you enter the State ID number individually to save the information, not by bulk. Here's how:

1. Go to Edit.
2. Select Preferences.
3. Choose Tax: 1099.
4. Under the Company Preferences tab, select click here from the option asking If you're ready to prepare your 1099s.
5. Click Get Started.
6. Hit Continue.
7. Choose whether you manually or electronically file your 1099s.
8. Click Save & Close.

Once done, you can now prepare and file your 1099 Misc form including your state ID number.

For your reference, I've included a screenshot below and a guide in preparing and filing your 1099 Misc form.

Please let me know if you have any other questions about 1099s in the comment section below. I'll always around to help you.

I did exactly what you said and the State and Withholding number still did not print.
