Question

I exercised and held ISOs. Do I need to fill both 3921 and 6251?

I was granted the options in early 2016, and I exercised the ISO mid 2018.

If you didn't sell ALL the shares acquired by year end, then you do need to put that information into TurboTax.

Tell TurboTax about the shares unsold at year end using the "ISO Exercise & Hold" interview.  TurboTax will make an adjusting entry for these unsold shares (# of shares unsold) x (per share "spread" between FMV and strike price) on Form 6251.  That interview will ask for your Form 3921 information.

Thanks for the answer, Tom.  

I actually didn't sell ANY options yet - just bought them and am holding ALL of them.  Do I still need to fill in both 3921 & 6251 forms?  I ask because TurboTax is counting the amount twice against me.  Please, let me know.  Thanks!
