In the past, the software automatically uses the credits that do not carry-forward first (tax laws are "usually" written that way).
You just enter all the possible credits you have, and then check your printouts when done to ensure they are being applied correctly before you actually file.
The tax software usually has a lot of bugs early on, so don't file until at least March 1.
