Can I amend my 2019 Tax return now, using TurboTax and then file by mail ?

[DoninGA]

TurboTax does not support tax year 2019.

You will need to seek out a local tax professional to assist in completing the 2019 amended tax return.

Note - If you are amending a return for a tax refund, the refund will not be paid as it is beyond the three year limit from the due date of the 2019 tax return.
