Can nondeductible contribution basis for inherited RMD be skipped & saved?

Because TurboTax doesn't support the ability to e-file if you have a RMD from an inherited IRA with a nondeductible contributions (see:  https://ttlc.intuit.com/community/taxes/discussion/feedback-need-support-for-distribution-from-inher... ) , does anyone know if I can skip putting in the basis this year, and just "save" it all for future years?

 

Ignoring the nondeductible contribution basis this year doesn't cost me that much this.  But if by skipping this year, I throw away the entire basis for all future years, that does cost me quite a bit.

 

Everything I've read says not to file by paper this year.  Perhaps next year, either the IRS will be able to handle paper returns again, or TurboTax will have addressed this problem.
