For reference, Rem & Ram's ages were listed as 17 in both versions so that should give you an idea about the time frame in reference.

Further, the statement "I will be nineteen this year" cannot be true in regards to Reinhard because it implies his 19th birthday is later that year, but his birthday is January 1st, the very first day of the year. The only way in which it can be even remotely true is if he turns 19 in few hours or so.

Basically Reinhard is 19 for the first 4 arcs and 20 onwards.

Edit: There is also this from Rom's 2018 birthday Q&A confirming that Reinhard is 20:

Q: What does Old Man Rom think of Master Swordsman Reinhard?

A: While thinking of him as dangerous, he also thinks that 'he's still just a twenty-year-old kid'. Yes, except for the fact that their real world given birthdays don't necessarily match up with their Re:ZERO world ones. For instance Subaru says he will be turning 18 that year, but his arrival date to Lugunica is the 14th of Tammuz according to LN Volume 1, the gregorian equivalent of that being June-July (and the narration also plainly states that it's the middle of the year). Since his birthday is April 1st, his stated age would make no sense. The birthdays are mostly for Q&As and wordplays and aren't to be taken into serious consideration when calculating character ages.

Furthermore, a direct statement from Reinhard in an actual Side Story, in a line dedicated to his age, is more reliable than a Q&A.

And even putting that aside, the wording in that answer was 二十歳ぐらい (hatachi gurai). ぐらい  (gurai) signifies "around" in Japanese, so the most accurate translation would be "he's still just a kid around 20 years old", which doesn't exclude a 19-year old at the time the question was asked. You may look it up or ask translators for the gurai thing.

All in all, sticking to what was directly stated in the SS is far more reliable, and the Q&A doesn't contradict it.
