The USB device issue has come up in prior years, where TurboTax was requesting license/activation code every time the program is opened and it appeared to be caused by the software looking for a device that was plugged into the USB drive when TT program was initially downloaded.
If you could identify what USB devices may have been plugged in when you initially activated the program and duplicate those conditions, the issue may resolve itself.
I am reporting this issue for further investigation.
In the meantime, you could opt to use another tool for calculating your estimated withholding and/or estimated taxes for 2025:
TurboTax W-4 Calculator - this is a standalone tool outside of the tax preparation program.
IRS Withholding Calculator
