Repay $16k EIDL Loan balance of deceased borrower who qualified for “Small Estate” in California?

My daughter died suddenly in 2023. She lived in California, as a freelance designer and had an LLC. Her assets were less than $184,500 which qualified as a “Small Estate” and did not have to go through court probate. I am her mother and managed the payments of funeral, cremation, all taxes, hospital bills and small debts. I also dispersed her life insurance, 401k investments, etc according to her will. Then I received a letter from the SBA saying she was delinquent in her loan payments. She had borrowed $30,000 and owed a balance of $16,000. I have no copy of the contract.

I called the SBA, sent them everything they wanted, including Death Certificate, verification from her CPA that all taxes are paid and the LLC is closed. I have no copy of the SBA COVID contract but was told by the SBA that she signed it personally (not as her business). Customer Service at the SBA said the estate is incurring interest for the late payment. There is $19,000 left in the bank but the SBA said not to send it until I hear if the remaining balance will be dropped. That was two years ago and since then, I have called and emailed the SBA every two weeks to receive an answer, without any success.

My daughter owed a balance of $16k but now it is much more, due to interest. Should I:

1). Continue to wait for them to contact me? 2) Should I send them the $19,000 left in the bank? 3). Should I apply for forgiveness?

The last time I called, the SBA verified that they have received all requested documents and they are waiting to be reviewed by the Treasury Dept.
