You are right. 21.5% is a high percentage. In PA there is no set percentage. Attorney's fees and executor's commissions are permitted if they are "reasonable", whatever that means according to a Judge. Some Orphans' Courts in PA will post a schedule of fees/commissions on a sliding scale.
I suggest contacting a probate attorney who practices in the county where the estate is being administered to review the probate documents to determine whether he thinks the fees are reasonable based on the work done.
While you have a right to receive a list of all services and costs incurred, if they do not produce this on your own you will have to hire an attorney to compel their filing of an accounting and production of documents. All costs they incur in legal fees and costs are paid by the Estate, and generally you will have to pay your own legal fees.
Mr. Bernick is correct - that is quite high, although as a percentage such a small estate the number may seem higher than it is - sometimes small estates have a disproportionate amount of work. Was this approved by a judge in an accounting?
