user23952: From the Penetrative Sutta, Nibbedhika Sutta, AN 6:63, translated by Ṭhānissaro Bhikkhu:
“And what is the result of kamma? The result of kamma is of three sorts, I tell you: that which arises right here & now, that which arises later (in this lifetime), and that which arises following that. This is called the result of kamma."
The translator seems to be trying to help the reader here when he adds (in this lifetime), but these are not the Buddha's words. I'm wondering if the three sorts are mentioned elsewhere in the teachings, possibly less ambiguously than here.

user19249: there is similar structure regarding the results in MN 136.

"Now there is the person who has killed living beings here... has had
wrong view. And on the dissolution of the body, after death, he
reappears in a happy destination, in the heavenly world. But (perhaps)
the good kamma producing his happiness was done by him earlier, or the
good kamma producing his happiness was done by him later, or right
view was undertaken and completed by him at the time of his death. And
that was why, on the dissolution of the body, after death, he
reappeared in a happy destination, in the heavenly world. But since he
has killed living beings here... has had wrong view, he will feel the
result of that here and now, or in his next rebirth, or in some
subsequent existence.
"Now there is the person who has abstained from killing living beings
here... has had right view. And on the dissolution of the body, after
death, he reappears in a happy destination, in the heavenly world. But
(perhaps) the good kamma producing his happiness was done by him
earlier, or the good kamma producing his happiness was done by him
later, or right view was undertaken and completed by him at the time

For more information about the mechanics of karma, I would investigate storehouse consciousness.
After reading an answer to another question - which references AN 4.77 - on this forum, I would perhaps advise with caution when investigating the precise workings of karma.

"The [precise working out of the] results of kamma is an
unconjecturable that is not to be conjectured about, that would bring
madness & vexation to anyone who conjectured about it."
