First off there is a horizontal line that doesn't belong in the profile you have created.
Secondly the two areas I circled are incorrect. The arcs should be tangent to the horizontal line.
Another option, instead of using PEDIT and the EXTRUDE command, is to create your profile using any combination of lines, arcs, polylines and/or splines then use the PRESSPULL command to give the object thickness.
