No that’s not true now, nor has it ever been, for selling your own personal use property. If I sell a camera lens online that I bought four years ago I don’t have to provide any receipt showing what I bought it for even in an audit. Estimated purchase prices are perfectly acceptable. You don’t even attach any documentation for this with your tax form in the first place. If all your transactions were selling personal use property just enter what got reported on the 1099-k for income and an offsetting amount for expenses.That's only true if you have a receipt, or some other way to prove the purchase price.you don’t owe any new tax.
If, however, you are actually running a business reselling things and you are calculating a profit or loss on your sales then yes you’d be wise to have documentation of what you purchased the items for because in that case if subject to an audit they will want to see justification for your profit and loss.
