A decedent's final 2019 personal income tax return was paper filed near the end of April 2020.  To-date, no refund has been received by the Personal Representative.  A Form 1310 was prepared, signed by the Personal Representative and filed with the Return.  The State income tax refund has been received.  Who do I contact at the IRS to check on the status of the refund.  (The IRS's automatic "Where's My Refund" does not allow me to do this.)
