Can someone please enter my rrsp contribution of $21905.07 on lines 11500, 23200, and 24640 because your program will not allow me to do it myself.

If you are using TurboTax CD/Download in Forms mode, click on the Forms icon in the blue menu bar and search for RRSP. Select RRSP - Registered Retirement Savings Plan and then click OK. You can now enter your RRSP contributions.
