There were no Ploughman £20 note outstanding by 1984.
The Central Bank of Ireland released the amount of each denomination outstanding in 1984, which was published in Irish Numismatics. The number of notes outstanding for each denomination were as follows:
£1, n=57497
£5, n=6559
£10, n=1506
All £20, £50, £100 notes were accounted for by then.
