Bought 1 btc at 30220.

Does Coinbase transactions CSV not show all your buys?  I'm 90% sure I bought some bitcoins on Coinbase once in 2020 Fall and once in Jan 2021 - but I don't see them listed!  I checked other sites I use and I don't see purchases there. Also I sent coins from Coinbase at two points (probably to Blockfi or Celsius to lend them) right after I'm 100% sure that I bought them.
