Try a conversion for 2018 and see how it works. You can try the software for free.

Word of caution, input is verrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrry different. Be sure to give it a try before committing. Do the 2018 conversion, transfer to 2019, recreate the return and see how much fun you have. You can do everything EXCEPT print or e-file for FREE! (not accounting for time spent)
