@HK89 , your question about what filing status to use ----
1. you could file as Married Filing Separate ( MFS) ----- this will require you to provide name etc. of your spouse ( whom was a Non-Resident Alien at the time ). TurboTax will require a Tax id for the spouse -- just enter a dummy SSN/ Taxid such as 123-45-7000. Then after the amended return is done, print it out and replace ( white out and write in ) the dummy SSN with " NRA". Then mail in the return. This is simplest path
2.You could file as Married Filing Joint ( MFJ), -- provide her current details i.e. SSN, and a statement signed by both of you that she wishes to be treated as a resident for the year 2020 -- since you were married by the 12/31 and therefore married for the year. This also means that any and all her income for the 2020 ( foreign or from US connected sources ---world income ) comes under the purview of the US taxes --- both Fed and the State. In such a case , she could be eligible for exclusion of foreign earned income or Foreign tax credit ( limitations apply ) if she had paid any income taxes to a foreign tax administration. There may also be tax treaty assertion that may apply ( thus you should tell me the citizenship of each of you and the country she was resident of for the year 2020 ).
Is there more I can help you with ?
