Upon speaking with a MD Comptroller Tax expert, I was told that not only would you need to file 502LU, but you must also send in a copy of your 1099G! So electronic filing seems like an impossible task unless TurboTax has a way of scanning in that form.
I inquired as to why the carryover Federal Adjusted Gross Amount from the Federal Filing was insufficient. No answer to that specific question. Just send in the 502LU and the 1099G. PERIOD!
I put in a call to the MD Comptroller's Ombudsman to inquire as to why they must have a paper copy of the 1099G with the filing when surely that gets electronically sent so they can audit everybody and dole out fines.
I have yet to hear back from them.
