Intuit will find new ways to make using your "older" QB for a long time.  For example, I use QB Pro 2020 and Turbotax Business for my 1120S corporation.  For years, I've imported data from Quickbooks into Turbotax.  Easy.  This year (tax year 2023) the Turbotax documentation says data can be imported from Quickbooks 2017 or later.  When my import failed, I contacted Intuit tech support.  After a wait, I was told only QB 2021 or later can be imported into Turbotax.  Then came the fun part. 

When my Turbotax numbers didn't "line up" with last year's, I tried to figure out why.  No matter how I tried I could not replicate the results of the tax year 2022 import from QB to TT.  I went with my best guesses and filed, although the time I spent trying to get the numbers right resulted in my being a few days past the March 15 filing deadline, and I got a penalty for late filing:  $235.  

So the next strongarming was turning off data transfer from Intuit QB 2020 to Intuit Turbotax. Bummer.  However, now I guess I'll look at other tax packages, some of which are from companies with accounting software too.
