Retirement tax questions

It is in the CF-1040 form. When I enter the dates for starting and stopping working from home due to covid it ask for mm/dd/yyyy. When I enter it in this format it changes my date to be mm/dd/yy then tells me there is an error. I've called turbo tax and they said that the form needs to be looked at by their IT department and wait 24-48 hours for it to be corrected. Its been twice that amount of time and i'm still having the error.
