Why can't go back to form 2210f (Schedule F) ?

[MayaD]

IRS Form 2210 (Underpayment of Estimated Tax by Individuals, Estates, and Trusts) calculates the underpayment penalty if you didn't withhold or pay enough taxes during the tax year.

Form 2210-F is a variation if you made at least 2/3 of your gross income from farming or fishing.

TurboTax will automatically generate Form 2210 if your return needs it.
