The IRS will be issuing checks weekly throughout the rest of July. The best way to find the answers to your question would be to consult the irs website. The link below takes you directly to the page regarding stimulous payments. I wouldn't recommend calling the irs about this. I tried it, and basically there are so many people with questions that the irs simply has an automated system to answer FAQ's. So for simplicity I would recommend the website.
