State tax filing

The threshold for a single filer is $75,000 AGI. I find this very wrong and am thoroughly disappointed in the State of MD. I, a single filer and was paid $37,400 in unemployment and was unemployed all of 2020. But, I have some financial assets that pay dividends and due to those and some capital gains my AGI for 2020 is just barely over the 75,000 threshold for a single filer. This is a real unfair process. Gov Hogan announces in several press conferences about Not taxing unemployment benefits. He makes No Mention about the threshold/caps on this tax relief for the unemployed tax payer... 

And the comptroller of MD has no clue when the 502LU will be available or the explanation for it...
