Hello and thank you for using Just AnswerHere is a chart that should assist you in understanding which form to use
2010 Tax Year and later(Filed in 2011 and later)
Form to File
Gross receipts normally ≤ $50,000Note: Organizations eligible to file the e-Postcard may choose to file a full return
As your organization has greater than $50,000 you can use either the 990 or the 990EZ. If your organization's information is simple thern use the EZ, even if you could use the EZ and instead used the 990 it would not be incorrect. The 990 is considered the "long form". You can use either. Both require the Schedule A.
