I would like to clarify if you've deleted the transactions from the For Review tab? Or, you've already added them to your bank register and you deleted them from it?
In the Excluded tab, you can Undo the excluded (deleted) transaction so you can Add them again from the For Review tab.
On the other hand, if they were deleted in your bank's register, the transaction will show again as For Review. From there, you can Add them back.
Here's an article that I got for you as your reference in reconciling bank accounts.
I'll be around if you need more help. Have a good one!
