FINALLY! Figured it out.
Delete BOTH the PCS W2 and the moving expense input under deductions. log out and log back in.
Reenter the PCS W2 info and include the P code with amount. It will ask you to list a new location and input city and state. It will also say that it will handle moving expenses later.
IMPORTANT!!!!
Now go to the search field and type "moving expenses" and click "jump to moving expenses" This will now fix the issue and link the 3903 with the PCS W2. For some reason if you just go back to deductions and hit edit moving expenses you will keep getting the error. You will notice that the amount (CODE P) is now auto-populated in government expense on the 3903. You will not need to reenter that amount.
Good luck and thank you for your Service.
