Amending State Return Due to Residency Error

[ocj]

I remotely worked with a Maryland-based company for 3 months of 2020. During this time, I was a part-time resident of DC. I lived in DC for a total of 8 months of 2020, then I moved to Florida. On my Maryland non-resident tax return (505),  I put that I was resident of DC. According to DC residency status, I was officially only considered a part-time DC resident for 2020. 

Because I put that I was a DC resident, and because of my 2020 income, I did not owe any taxes to Maryland for 2020. I'm worried that I should have actually put FL as my residency, since that is where I resided as of the last date of the 2020 tax year. 

My 2020 Maryland non-resident tax return has been accepted already. Should I file an amendment (505X) to my Maryland non-resident tax return? If so, is this something I can do through TurboTax, or should I file it myself?

No, you probably don't need to Amend your return.

If you reported your Maryland non-resident income and did not owe any tax, you would probably still not owe any tax if you reported you were a resident of Florida rather than DC.

If sufficient Maryland or DC tax was withheld on your income, you got credit for that tax on your Maryland return.  

Florida does not have Income Taxes.

That makes sense. Thanks so much for your help!
