Get your taxes done using TurboTax

If I did not file my 83(b) in 2020 for ISOs that I early exercised in 2020 (which will vest in 2021), how should I report this in TurboTax? Should I just not include it when I am reporting my 3921 I got for 2020? if I do include it, it incorrectly calculates the exercise as contributing to my AMT calculation. Thank you in advance!
