If your prior tax returns also had your wife as the primary taxpayer on the tax return, then you should keep that on your current tax return. Changing the primary taxpayer on your tax returns will cause issues with the IRS when it filed.
However, if this is the first year of filing as Married Filing Jointly, you should clear the tax return and start over to change the primary taxpayer.
If you have not paid for the online edition you are using, have not filed your tax return or registered the Free edition, then you can clear your return and start over. Click on Tax Tools on the left side of the program screen while working on the 2023 online tax return. Click on Clear & Start Over.
