Not right now. Conversion is from the prior year and the 2019 will be convertible shortly before the 2020 software is issued.  Just add a year to the statement on the link Lisa gave you.

"Please allow one business day for most converted files. We will begin offering tax year 2018 client data conversions with the first release of the 2019 Lacerte Tax program in November 2019."

@George4Tacks  so they'd need the 2018 TT file to be converted into a 2018 Lacerte file, then they could proforma 2018 Lacerte to 2019 Lacerte?
