Based on what you said I don't think you really owe any more tax. You probably need to amend the return to add the 401K 1099R and say you rolled it over to the IRA. Unless you put it into a ROTH IRA at the bank. What code is in box 7 on both the 1099R you got?
Did you pay tax on the bank IRA withdrawal? Is there a taxable amount on 1040 line 15b for it?
You might owe a penalty for taking it out early or if you are under 59 1/2.
