Get your taxes done using TurboTax

Not sure how you skipped the 2210 section every year  ... the program takes me to it every time I have a balance due of $1000 or more and tries to reduce the amount 3 ways over 6 screens ... did you never see these screens ?  The program doesn't HIDE this at all ... it even gives you the choice to pay it now or let the IRS bill you later ... also remember that there are 2 penalties ... failure to pay estimated payments  and failure to pay by the filing deadline ... only the first penalty does the program estimate based on your data entries ... the other is always computed by the IRS.
