I want to amend my return but idid not file with turbo tax, can i dowload the file on turbo tax and amend?

For returns not originally prepared in TurboTax, we do not have an option to download the file.  To amend, you will first need to re-create the originally return within the TurboTax software, mark it as "file by mail" (but of course do not mail it) and then begin the amendment process.

If you did not use TurboTax to prepare your 2019 return, it is possible to amend the return using TurboTax but it will really be a pain.  It would be better to use the software or service used to file originally.  If a paid preparer made a mistake on your tax return, that tax preparer should do the amended return for you at no charge.

In order to use TurboTax to amend your 2019 return, you need to purchase the desktop software for 2019 and re-create the return EXACTLY as it appeared when it was filed with the IRS/states.  Every line has to be the same.  Then you have to "trick" the software into thinking you filed by saying you will mail the return. (but do not mail it)   AFTER that, you use the software to prepare a Form 1040X, which has to be printed, signed and mailed to the IRS.  It takes the IRS about 3-4 months to process an amended return.
