You can upload the 1099-DA into TurboTax and then add the missing transactions manually. The IRS requires tax reporting of all income sources, whether they were reported on a 1099/W-2, or not. Adding more in gross income than what they've received on their matching copies, shouldn't trigger an automated underreporter notice. FAQ instructions to enter 1099-DA transactions for your TurboTax platform:
