I had to split and upload 35 separate CSV files with <100 transactions to get it to work.
I used CSV Splitter: https://www.erdconcepts.com/dbtoolbox/csvsplitter/csvsplitter.zip from https://stackoverflow.com/questions/37386246/split-large-csv-file-and-keep-header-in-each-part
UPDATE: Splitting let me get past the review process, but I could not E-File due to a transmit error. They have no clue what's going on.
