The problem might actually be in the worksheet for line 18. It looks like the worksheet was created to calculate the estimated tax paid in 2023 for the 2022 tax year. But it needs to include the refund received in 2023 for 2022. If there was no estimated tax paid in 2023 for 2022, then because the worksheet is missing the refund in the calculation, the worksheet will create a result that is the same amount as the refund, but as a negative number. The instructions for line 18 say that if the result is a negative number, it should be added (as a positive number) to line 14. So, that causes line 14 to be double the refund. The solution is for TurboTax to fix the line 18 worksheet, or failing that, just enter 0 in the last line of the line 18 worksheet in forms view.
