The Maryland state tax software did not work. It would not pull the correct data from the federal return and would not allow overrides. I had to file a paper return instead. As a result, after four months I still have not received my $10,000+ tax refund due to me.
Mostly easy to do and execute. Only two items required extra attention on my part, the IRA to Roth IRA contribution information and the extra government child handouts related to COVID.
