Turbotax 2020 has a bug entering the SSN for alimony recipient. The SSN field deletes the leading "0" of SSN and barf saying invalid SSN. The SSN field is designed wrong.

Whomever wrote the software for Turbotax 2020 version, this person is totally incompetent and uses wrong format for the information to be entered in SSN field. That is why it skips the leading "0" in SSN field.
