It asks for a military W-2 but ive already entered it in the previous W-2 entry , do i enter it again?

Are you active-duty military? or USPHS?

If the program does not recognize the DFAS W-2 as "military", your only option is to delete the W-2 and re-enter it. 

Use the "Delete a Form" tool to remove the DFAS W-2.

See: How do I delete forms in TurboTax Online?

After deleting the DFAS W-2  log out of the program. When you log back in, use the Delete a Form tool to confirm the DFAS W-2 has been removed from the list of forms in your return. Then, go to the W-2 interview and re-enter it carefully. The only reason the program should have missed the military W-2 is if the FEIN was incorrect.
