safe harbor for small business election

Using Turbotax Business 2021 and federal review says I need to attach SafeHarborSt for efiling.  It says to go to "efile menu" and select "attach pdf files".  The only attachment shown is the 8453-PE I created.  If I go to forms, both the De Minimus Safe Harbor and Safe Harbor Election for Small Taxpayers election forms are shown as part of my return.  How do I get this done so I can get the filing over with??
