License code used twice on same computer

Hi. I purchased TurboTax Deluxe Download last month.  I installed it on one laptop. License was activated at time of installation last month without issue.  I have been using TurboTax without issue for almost a month inputting information as my documents became available.

 

Everything was fine with TurboTax until today when TurboTax installed another update.  As the update installed, the status bar showed percentage of progress.  As the bar ran through 30% to 40% up to approximately 93 %, several multidigit random number strings appeared in the status bar in place of the percentages.

 

This did not happen with any previous updates.

 

When the update installation completed, Turbo Tax displayed my license key and said it needed to be activated.  Since it was the only way to get back into TurboTax, I hit OK.  At that point it told me I had now used 2 of 5 computers.

 

I'm still on the same computer I installed it on last month.  

 

Why would it count one laptop as 2?  I will be installing it on another computer in a few days, and I don't want issues with the program telling me I will then be on 3 computers instead of 2.

 

I am concerned that if this issue happened once it could happen again and continue to reduce my number of available computers until it reaches zero.

 

Any help from anyone, including TurboTax, in restoring my number of available computers at this point back to 4 would be greatly appreciated.
