NONE OF MY TURBOTAX SOFTWARES FROM 2006 TO 2019 WORK ANYMORE AND I NEED TO USE THE SOFTWARE TO ACCESS RETURNS!

I feel like TURBO TAX is ripping me off making sure none of the software I paid for from 2006 to 2019 works anymore. I called to get help but apparently not only can no one help me open software from prior to 2020 Turbo Tax has also made it impossible to open PDF's of your own tax returns prior to 2020 that were made by the TT software that are secured with your license key for the software. They changed the number of digits in the license code in an update and after the mandatory update the license code no longer works because it is only 14 digits instead of 16 digits. This is so awful and I feel so betrayed by TurboTax. I need to access old returns for important reasons and they are making it impossible. When they sell the software they do not say you are buying a 3 year license. They say you are buying the software. I've been an Advantage member for over a decade and am going to look for other software to do my return. Taxact may be ok but I want to do my return on my own computer not online. If anyone has a solution to this or can recommend a better software to use for home and business, I have a schedule C, please let me know! By the way most of the years that no longer work were made with software that doesn't require a license key. They just made an update that makes them no longer work. I have the software on old computers with the old original software that it worked on. The software required an update and once updated stopped working. This is apparently not just a problem on Mac computers.
