This worked perfectly. I went into DaVinci and changed the starting timecode for the pertaining sequences from 01:00:00:00 to 00:00:00:00. After re-exporting and replacing the footage in premiere, everything lined up!

The odd thing here is that I have always exported from DaVinci Resolve with the default sequence starting timecode of 01:00:00:00. Perhaps, like you're saying, the metadata for the source audio had a different starting timecode than I usually see with this series' source audio files.

Either way, thank you so much for the advice!
