I accidentally entered the wrong date of birth of my efiled return. When the IRS rejects it, will I be given an opportunity to correct it with Turbotax?

Yes, when it is rejected you will be able to make the change.

Yes----when it rejects you can correct the DOB and re-file.  But you have to wait until the IRS rejects it.  The IRS will begin to accept/reject returns on January 29.  Do not try to fix it now.  Wait for the rejection.

It's also a good opportunity to wait a few weeks after it is rejected....to re-evaluate what else you might have missed before e-filing again.

Any bank interest, 50cents or greater, should be entered as a 1099-INT from that bank...Any other tax forms you "forgot" about, or received at the end of January . or early February (many tax forms are issued late in the month and show up the first week or two in February.
