@cdpalmer3    Don't let that happen again ...

Please try the steps in the TurboTax FAQ TurboTax 2019 and TurboTax 2020 requests license activation at every launch to see if it resolves the issue. If they do not, please reach out to TurboTax Customer Support for assistance. 

Also be aware  ... the configuration of your system must be the same everytime you activate the program  ... some have said that having something plugged into the computer makes a difference.  So if you had  something plugged into one of the thumb drive ports when you initially installed the program or if you didn't then remove it.
