This is mainly a user community forum, so we can't see exactly what you were charged for that would explain that first fee of 39.99 on 2/28.
See the above discussion for some possibilities.
Or did you actually pay for Deluxe at 39.99 for Federal return on February 28, but were still charged a second time for 59.99 on March 4 after the Deluxe price increase which took effect March 1?
In any case, it's not likely to be resolved here in this forum. Here's how to reach TurboTax Support with any fee issue so you can discuss your situation to see what all you were charged for, and to remedy the situation if necessary.
