Get your taxes done using TurboTax

I have a "Free" version test account...I just entered 4 x $100 Quarterly estimated payments. 

No prompt occurred to force me to update...at least not yet.

 

Make sure you enter the exact dates you paid them....don't use the default deadline dates.

Perhaps, if you were entering state estimated tax payments, your total "Itemized Deductions" reached the level wehr you had to use the Deluxe version to get to use those "Itemized Deductions".
