I did the following, successfully... maybe i'm misunderstanding or maybe you're running into something specific to your machine or situation.

- In 2019, Used Tools -> Billing -> Rates Per Form, set Form 1040 Worksheet to 125

- In 2020, Used File -> Transfer -> Transfer Preparer & Billing Info... to import 1040 Paid Preparer, Billing, etc

- Confirmed via Tools -> Billing -> Raters per form that the $125 was transferred

What are you doing / what are you seeing?
