Tax Preparation for 1120 H

Our HOA has overpaid to have our taxes prepared for the last several years and I believe that this can be prepared without their assistance. We only have 17 members with an HOA fee of $100 p/year. In addition we also have a loan taken out in the HOA Name that was used to pay for paving our lane that member are responsible for paying 1/17th of the payment. I have reviewed prior year preparations and cannot make sense of the figures prepared by our CPA. Should the 'Total Exempt Function Income' consist of all money taken in over the year for dues and loan repayment? Our only expenses are for snow removal and legal fees for a member that is in default. I do have an accounting background so it shouldn't be this difficult.

Thanks for your response. I am not sure where the numbers came from that the previous preparer used so I wasn't confident in how I read the tax instructions. Now I can move forward and be confident in my returns.
