I too am having this issue. Before shut down I went to the local IRS building and was told that the PIN is needed to file for safety -identity theft- to file. The thing is no matter how you file you will need this number. In my case I never got a letter from IRS Dec.2019 or Jan. 2020 so I haven't been able to file after rejection notice. To retrieve the PIN you go to the website which will lead you to a sign in or registration. I tried this-between entering my info the AGI required or PIN this did not work for me. It wont continue after or accept the info. So after trying to research and fill out forms the conclusion I have come to,because you cant call anyone is 2 options you can google search for an IPPIN reset form that could be mailed for faxed(process can be long). Or have someone file the taxes for free print them off and mail them in mind you because you need a PIN you have to include multiple forms of ID to be sure it is you -SSI card, DL ID, and or something photo copied to send in to the IRS with either option taken. I hope this helps as there is no other way around this until there is either a new link that helps reset the PIN because there is no other way but ti call or send in a request for if say you cant retrieve by form or login. Stay safe everyone.
