In TurboTax Online any change that you make is saved immediately and permanently. There is no backout or undo. So there is no way to bring back a form or schedule that you deleted.
If you are primarily concerned with the information that was transferred from last year, you could clear your tax return and start over. That would allow you to redo the transfer from last year. But everything that you entered so far this year would be lost. See the instructions at the following link to clear your return and start over.
