The nature of your situation makes it unlikely that we can help with your issue without actually seeing your tax return, which we cannot do on this forum.
If your product qualifies, I would encourage you to contact TurboTax phone support, where, with your permission, you can share your screen with a live TurboTax agent to see what the problem is.
