- Can I include my 2008 1040-ES Voucher #1 with my 2007 1040 tax return & payment? Or must I mail it separately?
- I have the 2008 1040-ES vouchers from TurboTax printed but I am going to pay a different amount. Can I just cross out the printed amount and write the amount I am paying? Or should I just print out the PDF from the IRS website?
