The late Paul Ritter has also received a posthumous nomination for Friday Night Dinner.
The TV chef became an internet sensation with her pronunciation of the kitchen gadget last year.
Sian beat Fleabag co-star Phoebe and other nominees to win Female Performance In A Comedy at Friday's socially-distanced event.
Richard Ayoade hosted a ceremony like no other ever seen before.
The Crown, Fleabag and Giri/Haji are also among the top-nominated shows at this year's awards.
Line Of Duty, Coronation Street and Love Island are also in the running.
Due to lockdown restrictions, the ceremony will be going ahead with a few key changes this year.
The ceremony had been scheduled to take place in May.
From next year, nominated shows must feature at least one prominent figure from an "under-represented group".
Barry Chuckle and Love Island are both Bafta winners.
