There was no perjury.
Carrol made a mistake in a first deposition.
The mistake was later caught by Kaplan (her attorney) who informed Carrol of the mistake.
Kaplan (her attorney) notified Trump's attorney's of the discrepancy and Judge Kaplan (no relation to the Carrol's attorney) allowed for a follow-up deposition on funding.
The mistake was found by Carrol and her team, who notified Trump's team, and a corrective deposition was held.
Any attempt to charge her with perjury will not succeed, but charges are not the goal - harassment is.

"At Ms. Carroll's October 2022 deposition, when Carroll I (but not this case) was pending, in response to a question asking whether she was "presently paying [her] counsel's fees," Ms. Carroll responded that hers was "a contingency case" and said that no one else was paying her legal fees. App'x at 1188. On April 10, 2023, however, Ms. Carroll's counsel disclosed to Mr. Trump's attorneys Ms. Carroll's refreshed recollection "that at some point her counsel secured additional funding from a nonprofit organization to offset certain expenses and legal fees." Id. at 1191. In response, the district court permitted defense counsel limited discovery into the litigation funding, and Ms. Carroll's knowledge of it, while reserving judgment on the relevancy of evidence relating to the issue."
