Can I start over importing 2018 data but preserve my deductions?

I have begun doing my taxes in 2019 TT. I entered numerous deductions in a return I started from scratch. I did this so I would not have to manually delete a lot of deductions from 2018 when I brought in the 2018 TT return data. But now I have changed my mind, I would prefer to start over from my 2018 return data, yet nt have to retype all the deductions. Is there an easy way to do this? I don't see any way to for example  export my 2019 deductions....then I could start over, bring in my 2018 return data, delete all the 2018 deductions, and then import the 2019 deductions I previously exported. Is there some way I can accomplish this? Thanks!
