Ok, let's distinguish between clearing TurboTax errors and misreporting your tax liability. If I have 10 transactions that are all wash sales for disallowed loss of $0.49 cents each, my aggregate disallowed loss is $4.90, which rounded is $5. If I round all the wash sales to $0 first, then aggregate, my disallowed loss is $0. As you can see, in doing so I have "stolen" $5 of deductible losses that should have been disallowed.
