I don't have a 1099-R,but received an Inheritance Executor commission check. Do I include this as income and where do I include this?

This Executor Commision Check would be posted as regular income.

If you don't have a W-2, it can be posted to Other reportable income. 

Start at Federal

1. Wages & Income.
2. Scroll to Less Common Income.
3. From the drop-down select Miscellaneous Income [Select / Revisit].
4. Choose Other income not already reported on Form W-2 0r Form 1099.
