Retirement tax questions

do you have more info on what these small transactions are? - not sure what WHIST might have meant - you should go back to your original transaction information for the dates and cost basis and enter those details, tho $0 should be allowed for box 1e if valid (can be the case on expired short put for example)

 

if you input these as a 'sales summary' it will likely trigger the need to send your 1099-B to the IRS, it's better to input as 'one by one' to avoid the mailing (same with wash sales, AMD etc).
