To VolvoGirl: As stated in my OP, we haven't received a full refund, and the IRS refund status search returns "it is still being processed". Also, the following is in the IRS weblink I posted in my reply: "The interest payments, averaging about $18, will be made to individual taxpayers who filed a 2019 return by this year's July 15 deadline and either received a refund in the past three months or will receive a refund. Most interest payments will be issued separately from tax refunds." For us, "or will receive a refund" and "separately from tax refunds" are the relevant text. The small amount we received is consistent with interest calculations from that link.
What kind of Volvo? We have a '83 240 turbo; still looks and runs great.
