One can only preview the 1040 and not any other forms / schedules.
The 2 changes I'd like to make are
1) Foreign accounts, max value in 2021, and total value in 2021. The max value of my foreign accounts inaccurately reports and overstates my total foreign value, its not just a summing up... I'll most likely have to just fill these forms out manually from the IRS site so they are correct.
2) I've decided to make additional HSA contribution for 2021. This shouldn't require a 1040x, especially before I've sent in my taxes.
