Can I manually enter a 1099-INT that my investment bank has not provided with interest earned greater than $10?

yes 

Log in to your TurboTax Online account and open your tax return.
Navigate to the "Wages & Income" section from the main menu.
Scroll down to "Interest and Dividends" and select "Start" or "Edit."
Choose "Add a 1099-INT" to enter your interest income manually.
Fill in the required information from your 1099-INT form, including payer details and interest amounts.
Review your entries for accuracy and save your changes before proceeding with your return.

Yes, you can and you should do so.  According to Publication 550, "you must report all your taxable interest income even if you do not receive a Form 1099-INT."

You can enter the information manually as if you had actually received the 1099-INT using the box for Box 1 - Interest income.
