Tax return filing pending

Hi. My wife and I filed married filiing separately using each one turbotax accounts. When she filed her taxes on Sunday, we received an email about a security hold for 48 hours. At this time the status of her tax return e-file with the irs is still pending. Does thay security hold means that turbotax has not sent her tax return to the irs? If not, what happens if they send it after today’s deadline?

 

thanks
