normally for Turbotax to pull in 2020 numbers you would have to be using the same account the accountant used for 2020. if the accountant was using Turbotax and charging you a fee, they were in violation of the license agreement which prohibits commercial use of Turbotax. tax returns preparers preparing returns for others for compensation are supposed to pay for and use LaCerte if they want to use an Intuit product.
