Has anyone else had a problem with the (QEF) Quick Employer Forms transmitting 1099-NEC forms? I e-filed them on Jan. 31st but they didn't get submitted until Feb. 1st.

After clicking on the E-file button, it showed Submission in Progress. I printed my forms and emailed them to my vendors. I received an email from Intuit that they were submitted on Feb. 1st- late. The transmission slip that prints after all the forms doesn't have a date or time stamp on it. How do I prove I e-filed them on time.
