TurboTax 2020 rounded each trade from my 1099-B upload. The cost basis/proceeds do not match my 1099-B by a difference of $18. Is this normal?

After uploading the 1099-B, both the cost basis & proceeds do not match my 1099-B due to rounding of each individual trade, leaving a difference of $18 between TurboTax and the reported 1099-B values. Is this expected?
