I'm sorry to hear that you're still having issues. I called and spoke with another IRS agent today and they informed me that the "Your Spouse as a dependent" box being checked would not impact your payment... it would just delay it being sent; which is what happened to me. The IRS agent also told me that if that box was in fact checked... your spouse would be the one not receiving the payment (which isn't true because my wife received her check in June).
To be quite honest, it seems like there is so much GREY area regarding the stimulus payment that not even the IRS fully understands the eligibility criteria. I would encourage you to keep checking and make the calls to the IRS to see what is preventing or hindering you from receiving the payment.
I was originally told by the IRS the Spouse dependent box was checked and that prevented me from getting the payment.. turns out that's not the case at all. Just a few minutes ago I entered my 2018 tax information and entered my bank account information and that was that.. they'll be sending it soon.
Best of luck and keep moving forward! :]
