Getting started for next year

I have a small restaurant business and I have always had an accountant do my taxes but I am tried of paying so much.  My 2019 taxes were just finished and the bill about knocked me out.  Is there a way I can load the data from my 2019 taxes into turbo tax now so I can file 2020 on my own.  I use quickbooks online (which my accountant said caused them more work) and would like to sync them up somehow.

 

Any guidance is appreciated.
