If you have already Efiled your return and it has been Accepted, you will need to wait until you receive your Refund to mail in an Amended Return.
You don't have to enter your 1095-C, and if your daughter's 1098-T doesn't qualify you for an Education Credit (Box 1 amount is larger than Box 5 amount), you don't need to enter it TurboTax either. Just keep them for your records.
Definitely your lottery winnings will probably change your return, though.
