The Personal Representative/Executor (which may or may not be the widow) is required to file an estate income tax return, Form 1041 if the estate had income- such as interest or dividends in the decedent's name that have not been transferred to the beneficiaries. See the 1041 instructions for the income threshold.
If the wife is the beneficiary, the if she puts the interest and dividends, etc. on her 1040 with designation (interest income example) "XYZ Bank Nom Fr 999-99-9999 .... $1,000" would that be also a correct way of reporting the income, so that she does not have to do a 1041?
Not really. But if she did that and IRS is now looking for a 1041 you could explain that she did that and at least the income was reported and taxed.
