What do I enter for "total of all your payments and withholding" from 2018 if I don't have my tax return documents with me?

I am sorry we do not have access to your return to see exactly why you are being asked these questions.  Are you being asked these questions for computing under payment penalties?  If so, you do not need this data to finish your tax return. 

If you chose to electronically file your tax return you will still need your 2018 tax return, as the IRS requires your 2018 AGI for security purposes. Here is where you can find your 2018 return:

If you used TurboTax last year you can view your 2018 AGI by selecting Documents on the left hand side of your screen.  Select View Documents from: Select 2018 on the drop down menu.

OR

You can obtain a copy of last year's tax transcript online using IRS link:   Transcript 

OR

If you have a copy of your 2018 tax return, your AGI is located on line 7.
