What is a .T20 file?

A .T20 file is a specific type of file used to store tax return information. It is created by the 2020 version of H&R Block Tax Software, which is a program designed for both Windows and macOS computers. This software is commonly used in the United States to help individuals prepare and file their tax returns. The .T20 file contains important tax-related data, including personal information of the user and details from state and federal tax forms for the year 2020.

To open a .T20 file, you will need to use the H&R Block Tax Software from the same year the file was created, which is the 2020 version. This ensures that the file is compatible with the software and can be properly accessed and edited if necessary. Other versions of H&R Block Tax Software or different tax software programs may not be able to open the .T20 file correctly.
