Should I be worried

I joined this June. Our team has two chunks, one is doing project M and the other doing project H. For the first three month, project M was my ramp up project and manager said I did well. In the mid of October, my mentor told manager that I have code quality problem, writing too fast with bugs in diff. Manager talked to me once and pointed out, which I appreciate. Then the last quarter began, I was assigned both project M and project H work, project H is very coding heavy because of the design pattern and for project M, the tl didn't give any input, I would have to basically guess in the doc, according to the previous pattern, we can present the doc, let people comment, at the same time, start to work(it's building a dashboard), but my manager insist that I need to get a signoff from the project M tl, which I previously actively ask for input, no response, after the dashboard was drafted, the tl was not satisfied and told manager, manager told me he will let other people take over this. That's part one.

Part two, the tl from project H provided detailed guideline and I raised diff in time, but the person was really busy, I can't get my diff reviewed, for a whole week, I only got one review, even though the work has a target date, but that seems not to be meaningful with the sluggish review process, I also asked other team members involved in project H to take a look at my diff, only one person responded after three days. The feedback from this tl is that he can't approve my diff fast. Then the manager think it's still my code quality issue, which I paid extra attention after last feedback, so I was really confused with what he said. The diff review process is always an issue, it was brought again and again during team meeting, but nothing was done to really solve it

The PSC is looming, good part is that I don't need to participate it since I'm TNTE. But I still sense the atmosphere has changed from manager. I thinks the work assigning has some issue as I have never worked on project H before and because of this heavy coding task, I needed extra time for it, hence having no time for project M's dashboard.

Should I be worried at this team? I am not eligible to transfer now, what should I expect next year?
