When you enter the Form 1099-R from the original retirement account, you'll indicate to TurboTax that it was rolled over to another retirement account (the IRA), making it nontaxable. If the code in box 7 of the Form 1099-R from the original retirement account is G (which is likely the case if the bank forced you put the money into an IRA, suggesting that the check was made payable to your IRA instead of being made payable to you personally), the code G itself indicates that the distribution was rolled over. In this case the amount in box 2a of the Form 1099-R would be zero, indicating that the rollover is nontaxable.
If the distribution was made payable to you, the Form 1099-R from the original retirement account would instead have code 1, 2 or 7 in box 7 and would have a taxable amount in box 2a. In this case you would have to explicitly tell TurboTax that the distribution was rolled over, making it nontaxable.
