State tax filing

Hello,

 

Quick question.  I already filed my 2020 taxes but forgot to elect the De Minimus Safe Harbor $2,500 for two of my five rental properties for a new garage door ($800), blinds ($1,800), fridge ($1,900), washer ($500) dryer ($500) and garage door opener $250).  I usually use TT Premiere (rental properties and investments) and since I have never been able to find the election forms I just physically mail it in to the IRS each year.  I expensed each of these items under either other or repairs.  Since I did not file my Election what should I do?  Any suggestions?
