So, got tired of waiting. H&R told me I had to pay an extra $60 for a total of ~$110 as soon as I got to covering last 3rd of 2020 payout (i.e. 8915-f). TaxAct also didn’t have form. Used FreeTaxUSA, finished taxes incl 8915-f, efiled, and it has been accepted by the IRS. My taxes are not very complicated, a few extra forms and schedules. Another option is Free File Fillable Forms from the IRS. No guidance, but if you know the forms you need you fill them out, it does simple math and transfers amounts to other forms e.g. 1040. Used it last year instead of waiting
