I have a 1095B not 1095A. I worked for Federal Gov't and also have Tricare For Life. Was I correct in leaving the question blank?

If you are referring to having a Form 1095-A, then when asked if you have this form you should answer No.

A Form 1095-B is not entered on a tax return.

That form doesn’t have to be reported. You just have to answer “no” to the question that asked if you have health coverage through the marketplace.
