Get your taxes done using TurboTax

The link you provided is for personal income tax software.  We need the manual update link for TurboTax for Business 2020.  The only link I found on your website is for the manual update for 2019 and prior years.  What if I deleted TurboTax for Business and reinstalled it?  Would that fix the download problem?  Given the number of posts on this topic, TurboTax clearly has a defect.
