Under 'Liabilities', click on the Real Estate Mortgage. Ensure the field for Principal and Interest is filled in and repeat this for all Real Estate Mortgages. On the left go to 'Purpose and Property'. On the upper right you can fill in the taxes and insurance (along with HOA and other miscellaneous expenses related to the property). If you put the full payment in the Principal and Interest, then just put $1 in the taxes and insurance fields.
