I'm about to submit an amendment to my 2020 returns (both federal and state).
In reviewing my MD state return documents from TT, I noticed that neither the standard or itemized deduction box is checked. How could that even happen? My federal return has the standard deduction box ticked. As best as I can remember, in 2020 I answered all the prompts, and my returns were accepted. I owed no taxes.
Now I'm having trouble figuring out how to fill out the 502X without a claimed deduction. Is there a rule somewhere stating that you don't have to claim either for some reason?
