WHICH ADJUSTED INCOME AMOUNT TO USE

I filed my 2018 taxes using Turbo Tax.  I filed a regular 1040 form but then realized that some income had not been entered so I filed a 1040 Amended Form.  I am now  filing my 2019 Taxes (E-File) using Turbo Tax and it is asking for the Adjusted Income amount from my 2018 filing.  My question is do I use the amount from the 1040 form or from the 1040 Amended Form?

Thank You.
