I have followed your instructions to migrate QBO to QBDE in order to get Business Expenses imported into TurboTax 2020.
Today, the 30-Day Trial of QBDE is the 2022 version that does is not compatible with TurboTax 2020.
I have contacted QBDE support to request a trial version of 2021 but they said it was not available.
This thread needs to be revisited with up-to-date information on what people can do other than input all their info from QBO to TurboTax 2020.
You would think that Intuit would want to make deducting business expenses such as software subscriptions as pain-free as possible.
