Can you call me at 4/15/2019 5:30Pm

This is mainly a user community forum, not a direct route to TurboTax Support.  No one can schedule anything here.

You appear to be using the "Live Self-Employed Edition."   That product includes live on-demand help from a CPA/EA tax pro and a final review of your return, which they will sign.  Live Self-Employed is 199.99 for a Federal return and 44.99 for a state return.  If you choose to pay those fees out of the  Federal refund, there is an additional service fee of 39.99 (44.99 for California filers.)

The Live service is available during business hours 5AM-9PM Pacific (8AM-12 Midnight Eastern).  They are open this weekend.

Support opens at 5AM Pacific (8AM Eastern).  Once they are open, you should hopefully be able to schedule an appointment.  This is their busiest weekend of the year.
