I am trying to enter R&D credit on form 3800 from S Corp. From my research I know that the credit is not supposed to be limited by AMT if the taxpayer is considered Eligible Small Business, but the software keeps limiting it. The client has R&D credit carryover from prior years because previous accountant did not know about Path Act and Eligible Small Business. So, I am able to claim the whole carryover by choosing 2. G-Eligible Small Business Credit Carry-forward on 3800- general business credit worksheet, but 2020 credit is being limited. Does anybody know why. Any help?
