I have not been in the military service, only my husband has formerly been. So what am I considered?

For yourself when asked if you are active duty military answer NO.

If Bonnie is the civilian spouse, you indicate not in service.

Husband "formerly" ?   If he was in during any part of 2023, then you indicate that he was in service...assuming he will get a DFAS W-2 for that service for 2023.  When entering that Military W-2, there is a follow-up page after the main W-2 with a bunch of checkboxes....in the middle is one to indicate the W-2 was for active duty service...that needs to be checked in order to get either Free or discounted use of TTX software.
