Turbotax does not automatically deal with situations where income does not come in evenly each quarter
such as investment fund investor getting large fourth quarter income compared to other quarters. This
is main purpose of form 2210 to allow allocating income and tax paid quarterly and thereby not owe a penalty.
Fail to file form 2210 and IRS will calculate a penalty even if you 'MAY' not owe a penalty.
Form 2210 presently is in Turbotax but with errors and is not usable.
