Amending a Maryland tax return on Turbo Tax
I have what I believe is a Turbo Tax technical issue:
I am a New York resident since March 2017 after having been a Maryland resident.
I filed a 2019 Maryland NONRESIDENT tax return to recoup $1600 in withholding that was incorrectly sent to Maryland. I am preparing a Maryland form 505X Nonresident Amended Tax Return to amend the original return as Turbo Tax incorrectly included in Maryland income $5476 of my Capital Gains.
However, Turbo Tax will not let me change the Capital Gains amount to make it non-Maryland income. It appears to be a Turbo Tax technical problem, but I do not know who to contact. Please help.
