Does my 2024 tax return only require one signature?

Hello, for the year of 2024, I have to send FORM 1040 (U.S. Individual Income Tax Return), SCHEDULE B (Interest and Ordinary Dividends) & FORM 8938 (Statement of Specified Foreign Financial Assets) to the IRS by mail.
 
Could someone confirm that I only need to sign FORM 1040 - U.S. Individual Income Tax Return?
 
I asked the question because one time I forgot to sign and all the forms were returned to me ... Thank you in advance !
