I seem to have the military version of TurboTax (asking me about PCS and deployment), but I am no longer in the military. How do I change to the regular TurboTax version?

There is not a military version of TurboTax.  What probably happened is that the indicator for you being active military was selected in the My Info section of the program for your personal information.

Click on My Info and review your personal information and remove any indicator that you are active military.

If unable to remove the military indicator, then clear your tax return and start over.

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 2018 online tax return. Click on Clear & Start Over.
