Yes, you can use the 1095A Can we simply use the 1095A with my name on it as part of her return? Shared allocation is allowable.
Please see Allocation Situation 4 in the IRS instructions for Form 8962.
It doesn't matter who paid the premiums. Your fiancée won't be eligible for a retroactive tax credit if you paid full price monthly enrollment premiums and no advance tax credits. You could amend her tax return for 2019 to see what kind of credit might be applied. If you were to claim the payment of the premiums on your taxes, it will not impact the answer above unless you both amend your taxes, and even then, it may not be worthwhile. You would have to print your return and see what the difference is, but if you don't claim the payment of premium on your taxes, then you do not have to attach the 1095 to your return at all.
