As a South Carolina resident who received the State'd tax rebate last year, I cannot file my taxes until the IRS decides if that money is taxable. No discount?

If the fee increment is important to you,

you can e-File 1040 now and submit amendment Form 1040-X electronically no later until Oct 15th.

There is no charge to amend.
