Two follow-up questions: when I mail spouse MFS Maryland return, do I also sign her MD return? I lived in Florida for all of 2021 and did not have any 2021 Maryland income. Maryland form 502R directions for line 8 say to include spouse (mine) retirement income (502R line 8 should match federal 1040 lines 1, 4b and 5b). Is that required if spouse (myself) was not a Maryland resident for any of 2021? Thanks, again!
