Get your taxes done using TurboTax

Hi,

I have done this option for years.  You do not need to mail in a copy of your 1040 with the check, however, if you look at the 1040-V, it will state you need to write your social security number on the check.  I do not put my full SS# on the check, instead I put ...  Form 1040-V #xxxx with the xxxx being the last four digits of my SS#.
