A couple of things to note about the tax returns.
1st is the income on Sch E pg 1 is for residential rental property in Wilmington DE. Of note is that no depreciation is being taken on this property which is a bit unusual. For a rental income of 50,000 a competent preparer would have taken depreciation on the property. That does not compute.
2nd is that a search of the Entities listed on pg 2 reveals they were created in 2017, however additional information is not available from the Secretary of State’s office with the payment of additional fees.
3rd is a search of Maryland CPA’s on the Maryland State Board of Accountancy does not show the preparer however the firm does appear. All ID numbers have been redacted SSN’s of the individuals, EIN’s of the Corporations, PTIN and EIN of the preparer.
If you are interested dig further see what else is there that this cursory look missed.
