Thanks for very quick response. Yes, the alert was a wake up and surprising.Good to know I am good for year 2021 with the 2020TT Premier. I hesitate to upgrade my MacBook Air 2015 with OS Mojave 10.14.6. I also still use Excel for Mac 2011 ver. 14.7.7. This version of Excel not supported in new Mac OS such as Catalina. I have no need to update Excel as expensive & do not require all the functions. Now must try to figure out how I can continue into the future with these older versions of software or what can be substituted.
Thanks again
