"Special situations" on completing an Amended Return

I have to file an amended return for 2019.  I came to a screen with a list of Special Situations that you are to check if any apply.  The last one says:  "The IRS instructions want a printed text at the top of form 1040x for a circumstance different than listed above."

 

Do I go to IRS website and review the instructions for an amended return?  If so, where in the IRS 1040-x instructions would I find the other circumstances.

 

Thank you.
