Summary of Taxes Paid to Other States

Hello,

 

I am a US alien resident. In 2021 I was a part year resident in Baltimore (MD) (01/01/2021-11/30/2021) and part year resident in Washington DC (12/01/2021-12/31/2021). I went through my state taxes forms for Maryland and now I am trying to file the one for DC. There are two sections not really clear to me:

1- Subtractions From Federal Income, Part-year: enter any income received while residing outside DC. I suppose here I need to put the total salary earned in Baltimore from Jan to Nov 2021, right?

2- Credit for Tax Paid to Another State. In December I was living in DC but working still in Baltimore Maryland. Should I put the income for that month in this section? Is this a Double-taxed income? If so, where do I check the Tax Paid to Maryland on Double-Taxed Income?

 

Thank you very much!!
