Generally, yes, if you did not receive insurance through the marketplace, you can disregard the Form 1095-A section of your return. However, for some people who may not have received marketplace insurance, or may not be aware that they did receive it, their returns are being rejected automatically by the IRS. This is because someone on their tax return did receive marketplace insurance according to the IRS's records.
In that case, these forms have to be included with the tax return in order to electronically file. Otherwise, it would have to be mailed in and the IRS still may insist that their should be health insurance forms attached to the return.
The first thing to do is ensure no one on your tax return had marketplace insurance. They can check Healthcare.gov or the marketplace insurance provider in your state. If they have an online account, Form 1095-A should be accessible within their account. It is also possible that you are included on someone else's return, like a parent or an ex-spouse, so you would want to ensure that no one else has a Form 1095-A on it with you or someone in your family listed as a covered individual.
It's also possible that the IRS is just wrong. In that case, you can attach the form so that they accept the electronic filing using @Cynthiad66 step-by-step post above.
Entering $1 for your January premium will not impact your return and it should get past the IRS automatically rejecting it for not having the marketplace forms attached to your return. However, if Form 1095-A was issued for yourself or a member of your family, filing without the real form will cause a delay and possibly an automatic change to your tax refund by the IRS.
