Checking account entires not importing into my quickbooks for a period from may to july. I have not logged in for a while, but would only update the last two months??

You need to contact your bank and ask the bank statement file to import it manually into your QBO account. Another option, utilize SlickConnect as a workaround. It is designed to import into any bank or credit card in QuickBooks Online, so there is no specific setting needed.
