Second round proper
Quarter-finals
Semi-finals
Originally scheduled for March 2020, the two-legged semi-finals were postponed due to the COVID-19 pandemic. The FA declared their intention to complete the tournament, but with an uncertain timeframe. In late August 2020, they scheduled the semi-finals as single matches in September, with a date of 27 September for the final at Wembley. The final, alongside the FA Trophy final held as part of the same event, was to be among the matches trialling the return of spectators to elite football after the height of the first wave of the pandemic in the UK, but this was further postponed following new restrictions on gatherings in England that were enacted on 14 September 2020 as COVID-19 cases increased.----
