You are only supposed to add your fiancé to your marketplace plan if you can claim her on your taxes or you have a child together. If neither of those situations applies, you have to repay any premium tax credit that you received.
Since you were not supposed to allocate this policy, you may want to contact the marketplace to see if they can issue two separate 1095-As and you would only claim your amount.
If that is not an option, to repay the tax credit you received, enter Form 1095-A as it appears, except replace the SLCSP amount with 0 for all months that you were covered. You can then select the box that says I'm self-employed and bought a Marketplace plan in the Let us know if these situations apply to you screen after entering Form 1095-A.
A limitation of the TurboTax software is that it cannot both allocate a marketplace policy and calculate the premium you paid as a self-employed health insurance deduction. If your fiancé is required to file, then you may have to deselect the I'm self-employed and bought a Marketplace plan to allocate the plan. This would result in you not getting the deduction for self-employed health insurance.
