I was just about to ask you "which Herod?" about the Severus (of Antioch?) quote, but I see you already caught and removed it.
Sulpicius Severus gives the 18th year of Herod's reign, meaning Herod of Galilee, Herod Antipas. Eusebius gives the 19th year, Jerome changes this to 18th in his version of Eusebius's chronicles.
The Gospel of Nicodemus also gives 19 years of Herod's reign, and some versions make it the 19th year of Tiberius's reign too:
“in the nineteenth* year of the reign of the Roman Emperor Tiberius, when Herod was king of Galilee, in the nineteenth year of his rule, on the eighth day before the Kalends of April, that is, the twenty-fifth of March, in the consulate of Rufus and Rubellio, in the fourth year of the two hundred and second Olympiad, Joseph Caiaphas was high priest of the Jews." (translation of the standard Greek and Latin texts in Tischendorf by Felix Scheidweiller).
The Gospel of Nicodemus, also known as the Acts of Pilate, was a popular and well known text, the primary source for the accounts of Christ's descent into Hades, the harrowing of hell so popular in the literature, theatre and mystery plays of the late middle ages.

Scheidweller notes (p.543):
Note 3: “Manuscripts and versions vary between the fifteenth, eighteenth and nineteenth year of the reign of Tiberius. The year of the Olympiad (202.4 = 32/33) supports the nineteenth, which is also given in the Armenian version of the Chronicle of Eusebius. Eusebius dates the reign of Herod Antipas from the 2048th year of Abraham = A.D 14. Rufus and Rubellio are C. Fufius Geminis and L. Rubellius Geminus, the consuls of the year 29. This would correspond to the fifteenth year of Tiberius, the date of the crucifixion according to the oldest Christian chronology, based on Lk. 3:1
