Form 3800 Carryforward from K-1: general business credit

I have a general business credit carryforward from 2022 to 2023. On the 3800 form, field 4 on my 2023 fed return, the field shows as blank after I enter my 2023 K-1 from the S-Corp. The correct # is $38k or whatever, but Turbotax says I must "override the field" when editing the 3800 form to enter the correct number there. It then says the override will cause problems. If I double-click the field, it doesn't take me anywhere to do the computation. Where else would I enter that credit carryforward? I could just override it, but I'm trying to avoid discrepancies that will trigger an issue down the road. Thanks
