I live in California and because of storms my taxes are not due until May 15th. TurboTax will not let me enter this date because it's past April 18th

I have done my federal taxes and owe an amount due.  Because of recent storms in my county my taxes are not due until May 15th (https://www.irs.gov/newsroom/irs-california-storm-victims-qualify-for-tax-relief-april-18-deadline-o... ) When I try to electronically submit my taxes via TurboTax it refuses to let me enter a date past April 18th. The IRS announced this change about a month ago so how long will it take for TurboTax to reflect this?
