Deductions & credits

Any idea how to add to this amount if it doesn't equal your total premiums? Self-employed, bought for my family through the Exchange, but my son entered college and could get better insurance at a cheaper price through their group plan. So, my 1095-A does not include the amounts I paid in premiums there...and the box 17 on Schedule 1 appears "locked" when you enter 1095-A data. I don't qualify for subsidies...so don't really need the 1095-A, but Turbo Tax warns me the IRS will not accept the return without it if I bought on the exchange.
