My above answer is incorrect. The box 15b cannot be more than 15a or it results in a new error. You would either need to print all forms and worksheets in the online version to get the box 15a amount to enter or use the forms mode in the desktop version to view the 8606 and make the line 15b entry.
@dmertz Just to alert you to this issue.
