It is possible that with the other information you entered, you were eligible for a partial premium tax credit.  Do NOT ignore the 1095-A.

Thanks, but I can't find any information about partial eligibility. I couldn't get the tax credit before because the rule [(Are not able to get affordable coverage through an eligible employer-sponsored plan that provides minimum value (see questions 11 and 12)] didn't apply to me (I could get it through my wife's employer but it was more expensive than the marketplace). I'm worried if I claim that $900 incorrectly they will come after me to reclaim it in the future. I can't find any examples that are like my own.

Did you collect the $900? Did they ever come after you? I have a similar situation where after entering my 1095-A info my return INCREASED by nearly $5,000. I've gone back and double and triple checked everything and the was worried about it again so I went to amend the return and got the same result, so I canceled the amended return because they must be submitted by mail. Please help! I'm stressed out.
