Amended return - wife filed zero $ 2019 return, I (spouse) have yet to file a complete 1040

Yes, I'm way late...

 

Wife filed a quick online return to receive covid payments. She did not list any income or other financial info.

I need to file a complete married filing jointly return with all our financial info. Income, cap gains, interest etc... Can I accomplish this using 1040X? 1040? IRS instructions weren't clear to me...

 

Than you in advance!
