Hi I found that I was able to use Maryland's Form 502UP "Underpayment of Estimated Income Tax by Individuals" for my taxes, but helping someone else do theirs, found that North Carolina's D-422 "Underpayment of Estimated Tax by Individuals" was unavailable on Free Tax USA.
Am I understanding correctly that this seemingly equivalent form may not be available depending on the state? And I won't be able to file state taxes altogether, using Free Tax USA, if I need this form?
