SOLVED: If you started your taxes before the latest revision of form 8915-F was released, then your return will have the outdated form still attached and will be rejected by the IRS.
My return was rejected 3 times before. I went into "Tools" and deleted the "Corona Virus Distribution 2020" and "Form 8915-F" forms, then I went through the steps again to add/skip 1099-R's and add a Disaster Distribution for 2020. This worked and my return was accepted within 2 hours.
