Different tax refund when importing crypto from Robinhood vs manually entering summary sales

[Anonymous]

I've had the same problem in both tax year 2020 and 2021. Here is the problem:

I have about 250 crypto (BTC, DOGE) transactions in Robinhood. Robinhood also sent me a 1099B for these crypto transactions. All my transactions are short-term. Both my 1099B and the individual sales transactions verify this. Long term & undetermined term transactions reported in the summary table in my 1099B are all zeros. Only short-term (noncovered) transactions have some non-zero values. And, after importing the individual transactions into TurboTax from Robinhood Crypto, I don't see any long-term transactions; all transactions are short-term. The 1099B also shows the wash sale amount to be zero (though I'm not sure if the wash sale concept even applies to crypto).

If I import the transactions from Robinhood Crypto, then TurboTax computes the total gain as $378.56. If I manually enter the summary sale of crypto manually, then TurboTax STILL computes the total gain as $378.56. They both match to the penny (hence, no discrepancies due to rounding each individual transaction). So far so good.

But, even though the total gain associated with the crypto transactions is the same for both importing method and manual entry method, the total capital gain (short-term and long-term over everything including crypto, stocks, and mutual fund capital gain distributions) is different for the crypto importing method vs manual entry method. The importing method computes my total capital gain (over everything) as being $18 higher than the total gain via the manual entry method. As a result, my refund is about $8 lower for the importing method vs the manual entry method.

$8 is not that big of a deal but I want to be right because this exact thing happened to me during tax year 2020 as well. I don't remember which method I chose in 2020 (importing vs manual entry) but it resulted in IRS correcting my calculations. I want to avoid this for 2021.

Which method (importing vs manual entry) is correct ? And more importantly, what's going on? How is it possible that both importing and manual entry compute the same total gain to the penny ($378.56) for the crypto but then result in different total capital gain (over everything) ?

I made sure that nothing else changed. I didn't import anything else or manual enter/edit any other entry. The effect seems to be directly dependent on the importing vs manual entry of Robinhood Crypto.

if the difference is exactly $18, then it's likely you made a transposition error during manual entry. example 31 entered instead of 13  or vice versa.   we can't see what you did nor the documents so this is a guess.

either manual or import.  go to schedule D and total the sales and cost columns.   then do the same for the other method. this should identify where the difference arises.

I have thoroughly checked that there are no errors in manual entry. And, as I mentioned in the post, the manual entry total gain matches the imported transactions' total gain to the penny. So, there is no room for error in the entry part. The difference is in how TurboTax computes the total capital gain. This exact thing happened to me in the previous tax year (2020) as well and I just didn't notice.

It's even more unlikely that I made a similar manual entry error (I don't even remember if I used manual entry last year or not; could've been imported transactions for all the forms) that would result in a similar error for  two different years with completely different forms and numbers.

I don't get access to Schedule D until after I file. Is there a way to see Schedule D before filing? I am using online version of TurboTax.  If only I could see the Schedule D and the Qualified Dividends and Capital Gains Tax Worksheet, I'd be able to investigate further.
