Can I change the taxpayer designation from spouse to principal?
You certainly can! You would have to first detach the spouse’s return from the taxpayer’s return. Then open the spouse’s return and attach the taxpayer’s return to it. The spouse’s return will now be the principal return.

Thank you very much.
