Social Security Retirement Income & LLC Business Profits

I'm collecting SSI Retirement Income and own a brick and mortar business i.e. flower shop.

Last year for 2020, I paid myself as a W-2 wage earner $16,150.  The business made on Schedule 1, Line 3

$ 29,435.  Social Security Administration added the business income to my personal income W-2 and states they overpaid SSI Retirement Income by $9000 +.  SSA states this is an Overpayment.

This profit is working capital for the business, it was not taken out of the business.  

Do I owe this back to SSA or did they error in asking for an overpayment.
