I pay quarterly estimated taxes, am getting a refund, did not have a penalty, but got the 2210 rejection error when e-filing. According to IRS's instructions I did not need to file 2210. In the desk top version, I found that I could switch to forms view, find the 2210 form, right click and un-check Box A on 2210 part 2 by selecting override. Make sure it is gone from the forms list. If you go back through everything, it might show up again. My return was then accepted by the IRS.
