I used another service to file my 2019 taxes, and I want to use Turbotax to amend it. Do I just transmit again, or is there else I need to do?

you need the desktop TT software for 2019. you must enter your data so it matches the return you filed - line for line. some items may not need all the detail that was entered on the original return. however, since we can't see your original return we can't tell which items. it may also depend on what you are changing. then save it.  then reopen and click on the amend icon.  the return can not be e-filed it must be mailed in.

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 2019return, 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.

So, I think I understand what you're saying, but just to be sure: I can't just file a 1040X from the desktop software? Does the 1040X list or reference previous info?

You can't do the 1040X by itself.  You first need to recreate the original wrong return.  Then when it matches every line that you already filed you say to mail it.  THEN you can amend it.  You can use the Forms Mode to recreate the original return.  You will have to print and mail the 1040X.
