Small bitcoin sale ($14) gets rounded up to 1.04BTC ($97k)

I thought paying for something in BTC would be fun... Worst mistake of this tax year so far...

I purchased 0.00018 BTC for $17 and immediately sent 0.00015 BTC (FMV $14.09, cost basis $14.21).

When entered to TT Desktop Deluxe for Win11, it cuts the number to 0.0001, then converts it to 1.0E-4 and displays as "BTC (1.0E-04). However, when trying to edit, it converts it back to 1.04 BTC ($96737.91).

1. How to be sure IRS doesn't charge me for $97k short term gains

2. Are IRS auditors well aware of scientific notation?

But seriously, can someone at TT fix this?

what you see TurboTax display on your screen is 1.0400 - the E is missing. What the 8949 shows is 1.0E-4, which, in mathematical terms, is 1/(10/10/10/10) = 0.0001. You don't have a problem.  Your alternative might be to use the standard capital asset sales worksheet and enter 0.00015 BTC, or whatever.

I do have a problem. I know what scientific notation is. I'm also a software engineer and I know what happened here and I don't trust TurboTax to upload electronic forms to IRS correctly.

I see two bugs here:

1. TT uses wrong kind of intToString function, which falls back to scientific notation when it shouldn't

2. Then, it doesn't support scientific notation in their stringToInt implementation when reads it back

IRS would likely also have bug #2, so there's a good chance my 10^(-4) BTC will be interpreted as ~1 BTC.

Is this a correct place to report bugs in TT?
