If you received a 1095-A, then your answer will be yes.
However, if you receive a 1095-B or a 1095-C, you will answer No that it is not part of Marketplace.
I've done some research and it doesn't seem to be.
Marketplace plans must issue a 1095-A. Non-Marketplace plans issue 1095-B or 1095-C.
Only 1095-A must be entered into TurboTax. 1095-B or 1095-C is only held for your records.
