How do I enter information from form 3921 if some of the options were covered by an 83(b)?

[nORoSI]

My husband exercised some ISOs in 2022. Some of these were early exercised and included on an 83(b) and if I'm understanding correctly would not be subject to AMT calculations. If I enter the share information included on form 3921 TurboTax wants to calculate AMT on all of the shares. Is there a way to indicate that some of these shares aren't subject to AMT? If not, when entering the form 3921 information can I just record the portion that are subject to AMT even though the number of shares will differ from what was reported to the IRS on form 3921?
