After you file

Turbo Tax, H&R Block, etc. should have the technology to check to see if all your forms are done before they transmit your refunds.  When they did the check when I completed my Federal return it said it was all good even though I answered yes to the question about whether or not I received health insurance through Obamacare.  When they ran my state return they let me know that a form was not available for car depreciation and would not accept the return until the form was available, they even sent me an email when the form was available so I could finish my state refund.  If Turbo Tax could do that they can also let you know if you did not file a form such as the 1095A or 8962.
