I never advise using any of the "employer stock" step by step interviews as many people find them confusing and frequently come up with the wrong answer. There's no "income tax return reporting" requirements to use these step by step interviews except in one case, that being that the compensation was NOT reported on the W-2. But that's not your issue. In any case the ESPP step by step process would not be appropriate in your situation.
Instead of using the employer stock step by step process I'd say simply use the TurboTax default 1099-B entry form and then use the CORRECT BASIS against the proceeds of your sale of 45 shares. The correct per share basis is the same as the per share "fair market value" your employer used to come up with the compensation reported on the W-2 for the entire grant.
I'll admit I'm really not following your explanation of the transaction. The use of US Dollars vs. Swiss Francs, the rounding of some numbers and the exact numbers used elsewhere just makes it hard to follow. But I've told you what your per share basis is so:
Enter the 1099-B exactly as it reads. Enter the appropriate cost for the stock sold. The appropriate cost is (45 shares) x (per share FMV used by employer to calculate compensation.)
The typical "same day" sale usually results in a small loss due to selling commissions and fees, but that's not always the case. If you per share selling price was different than the per share fair market value used by the employer then you could have a loss more than the selling fees, and you could even have a small gain, which I'm guessing is the case here.
