I have a 1040 Schedule C client who has carried forward the Social Security Tips Tax Credit from prior years because he had no tax liability to offset it against in prior years.  The carried forward credit shows up in the Carryover Worksheet on Line 18 (General Business Credit), but it doesn't seem to be transferring into the current (2024) year's return -- only the Social Security Tips Tax Credit for the current year is populating on Forms 8846 and 3800. 

I'm assuming it's user error.  Can someone tell me how to get the prior years' credits where they need to go in order to claim them this year?  The client has great income for 2024, so would very much like to use them.
