Does having foreign bank accounts (assets don’t exceed $10,000) restrict me to use 1040 to file return and report interest earned? I satisfy 1040EZ conditions otherwise.

I don’t need to file 8938 or FinCEN Form 114 because my combined foreign accounts don’t exceed $10,000 but TurboTax is asking me to upgrade to deluxe and file 1040. Is it really necessary to file the longer form? Because I satisfy all the 1040EZ conditions. Is it because I need to declare my foreign assets on my tax return and that can only be done on 1040?
