The issue of 5 or 6 digit id pin, what is the solution?

Those are two completely different PIN's.   The five digit one is a "self-selected" number that you make up for yourself.   The six digit IP PIN is issued by the IRS.

If you have a 6 digit PIN issued to you by the IRS you need to enter it in order to e-file.  Go to Federal>Other Tax Situations>Other Return Info>Identity Protection PIN and enter the six-digit PIN.

Your signature ID (also called a self-select PIN) 

• Is a random 5-digit number you entered last year, right before you submitted your return. 
• You can use it to verify your identity on this year's return.

Thank you.  We seem to have and abundance of "pins" and I have now created new 5 digit e-file pins for myself and my wife and will see how this works out.   I appreciate your prompt response
