Try going to the Forms folder at the top of the portal (outside of the actual return you are working on). It should open up your actual working tax document and there most likely will be a flag at the disaster distribution pages, that is "missing information". Go to the top of that section, and scroll down until you find a box checked that you took distributions for previous years. If you unchecked it, the unfinished pages will disappear and the return will be able to proceed forward, escaping the loop.
