Form 8606

In years past I had to mail my return instead of efiling because Form 8606 was not generated for my inherited IRA that has basis. Last year, Form 8606 was correctly generated and I could efile. For this year(2024), Form 8606 is pulling a distribution from a different IRA (not inherited).that has no basis. How do I correct the distribution amount on this form? The carryforward basis for the inherited IRA is correct. I know that you cannot report IRA’s that are inherited and those that are not on the same Form 8606.
