Import 2018 tax return to TurboTax desktop before doing 2019 tax return

I did my personal income taxes with my accountant for the past several years including 2018. Due to covid-19, his office is closed and cannot do my 2019 tax return.

 

Therefore, I purchased TurboTax Deluxe 2019 and plan to do it myself. However, it asked me to import my 2018 tax return. I recall my accountant did give me a paper copy for 2018 tax. However, I cannot locate it. Even if I'm able to find it, I don't believe I can scan it to a PDF document that TurboTax recognizes.

 

My questions is: Do I really need to import my 2018 tax return to do 2019 tax return? For 2018, I got refunds from both the IRS and my state. Just wonder if it would make any difference if I import the 2018 tax return vs. not?
