Dave did you get a satisfactory answer to your question? I seem to have a similar problem (with no explanation from Quicken phone support.).
All of the duplicate entries can be found between 2/19/2020 and 1/20/2022. Most of the dups are cleared, but a few are NOT cleared. I have the latest Quicken update. My problem was first seen on 3/12/2025. In the morning one checking account had a balance of ~$3,000; in the afternoon the balance was ~-$120,000!
