Deductions & credits
When you select medical expenses, it should be asking you each time to select yes or no for medical expenses. I suggest updating the program to begin. Then, if it still refuses to allow the entry, you will need to enter the information in Forms mode on the medical worksheet. The worksheet allows entries so there will not be any overrides necessary. The form will carry to sch A and you can see that your return is flowing correctly. The forms are what goes to the IRS so those need to be correct. Overriding an entry will void the accuracy guarantee but the worksheet has allows entry.
