I'm filling out Form 5330 for my spouse, a self-employed sole proprietor, who made an excess contribution to a SEP-IRA.

Form 5330 asks for the following 3 values. I don't know what to provide here for a self-employed individual whose SEP-IRA is just an individual one. The instructions aren't helpful.

• Plan Sponsor
• Plan Sponsor's EIN (form field won't accept a Social Security number)
• Plan Number (apparently a 3-digit number)

Thanks for your help!
