You didn't give anywhere near enough information to evaluate your situation. But take a look at the top of Form 2210, at the flowchart that says "Do You Have To File Form 2210?" There are several situations for which it says "Don't file Form 2210." You probably fit into one of those situations. The IRS has enough information, without the form, to know that one of those situations applies to you. And TurboTax knows if one of those situations applies, so it doesn't prepare the form. You don't want to file the form if the IRS is telling you not to file it.
