How to change the values on form 8949 manually?

[Rob58Por]

Hi, Due to RSU sale and to correct the amounts reported on a 1099-B, I need to fill out the 8949.  However, when on the form, I am trying to change the values for the cost basis (according to 2021 Supplemental Information), but the fields seem un-editable.  Could you help please?  Unless this can be done via the "EasyStep".  Need help!!

IRS reporting rules require the institution to report the non-corrected basis on Form 1099B, even though the institution usually knows the actual corrected basis amount.

Because you know the corrected basis , then you can simply select the option to enter additional info on my own (or just select Continue if the on my own button isn't present) and enter the corrected basis on the next screen.

If you cannot do the above adjustment, you can delete the 1099-B and follow the Easy Steps, but it is easier just to do the adjustments.
