How to Include Extension form and New Jersey e-file

I filed for  Federal extension for 2020 using an IRS downloadable form 4868 and mailed it with a $200 payment.  I entered this payment in Turbo Tax in Other payments and Credits an it appears on Schedule 3 line 9, but I do not see form 4868.   New Jersey requires a copy of 4868 with the return.  How do I include form 4868 with my NJ state e-file ?
