Pull the basement toilet again and see if there is water standing in the line. If there is, there is still a clog. Run water in Kitchen sink and it should come up in the closet opening on the floor. You may have pushed the previous clog further down the line.
If you have a sewer clean out on the basement floor somewhere open it and see if there is standing water in the clean out. If there is, work from there as it will be closer to your clog towards the main sewer.
Also run water in other areas of the house to see if it comes up in the closet opening. This should pin point where your clog is.
