Deductions & credits

"If you are itemizing, and wish to take the deduction, TurboTax online or the download version will work."

 

Thank you for your answer !  Could you please clarify or explain how to do this exactly using the online version? - which deduction item I can enter a TEQ payment?   

 

Since I already started with the Online Premium version, I'd like to just use it to complete my return if possible, and I am take itemized deductions.   

 

Also, if I use the deduction to clalim for this payment, what other proof do you think the IRS will require? - just the desciption text be enough, or attach the bank payment receipt (does TurboTax actually send our receipt files to the IRS?)

 

Thanks again!
