MFS the only agi that should be entered is the one off your 2018 return. do not enter hers. if you file after 10/15/2019 try 0. sometimes nothing works and you will have to mail in your return. must be postmarked by midnite tonite if you owe.
if you were married on 12/31/2019 you and spouse may end up paying more in taxes filing MFS than filing joint
