The notification from the IRS in my email just mentioned that the filing season will begin on Feb. 12th.  It states that we can file 2020 returns at that time.  It didn't seem clear to me that 2019 was also shut down until then.  I do vaguely remember it shutting down in November.  However, when a corporate return has no issue begin electronically filed (the other day) it seems that the whole system is not down.  Is it only down for 1040 and 1041?
