Thanks Just-Lisa-Now for your prompt reply.  Probably your suggested solution and my overnight waiting to log back in has worked.  Please see below:

Pro Series Forms Bar Panel Not Showing Forms in Use

Feb. 22, 2020

Pro Series Professional 2019 TRs

Situation

Do not recall for sure but the mouse unintentionally went to the left side Forms Bar Panel and though the forms bar panel of the same width size (2 to 3 inches wide) stayed put but the form number of “Forms in Use” were replaced by light blue empty lines.

Attempts by me

Got out of the tax return I was working on thinking that this issue may be related to this specific tax return.  And opened another tax return but the issue was there.

Several times went to the Forms Bar Panel and tried to left click and right click the mouse.  But nothing seemed to work.

Do not recall whether I completely logged out and logged back in.

Finally, closed all applications including Pro Series Professional on my laptop

Posted my question in our very helpful community.  Had to leave office and home for a few hours and upon return I saw my helpful community friends responding very promptly.

Current Status

Just logged into my laptop and logged in my Pro Series Professional and notice that the problem is gone.  I am back to seeing the form numbers in the Forms Panel bar.

Conclusion

Not sure but the problem may not have been caused by my mouse but it was a Pro Series software problem for the time being.  I am not sure any other user in the same time frame experienced similar problem.  But Thank God and Thank to my helpful community friends, the problem is now gone.

Thanks.
