Unfiled taxes- 5 years

Good day all-

 

I need to file taxes for, 2018 to present.

 

I want to get done quickly.

Should I file electronically with Turbotax, the 22,23,24, available software, then file paper for the others?

I expect refunds for the electronic filings. Then, file amended after I file the paper returns.

All input is needed. 

Thank you.
