They have the right under the CCR usually to ask for attorneys fees and costs. Call them and offer to pay off the original amount, usually they will negoatiate a little.
That sounds rather high to me, too, but I don't know what fees your CC&Rs provides, when dues are over a year late or what the attorney has done to file the lien, or how many letters they wrote to you before the amount had risen to $2200. That said, most HOAs are willing to get members back in good standing and may be willing to give you a break. Be sure to ask for an accounting so you understand how this amount grew from just over $500 to $2200 and can determine what items seem excessive or not provided in the CC&Rs. They will probably agree to payments, since the dues and late charges are fully secured by their lien.
