Are you looking for something like the following code? Note that all of the data become characters because one of the original columns had characters and rotating the data causes every column to contain a character value.

DF <- data.frame(Taxo = c("T1","T2","T3","T4","T5"),
                 A = 1:5, 
                 B = c("V","W","X","Y","Z"),
                 C = 11:15,
                 D= 21:25,
                 E = 31:35)
DF
#>   Taxo A B  C  D  E
#> 1   T1 1 V 11 21 31
#> 2   T2 2 W 12 22 32
#> 3   T3 3 X 13 23 33
#> 4   T4 4 Y 14 24 34
#> 5   T5 5 Z 15 25 35
library(tidyverse)
DFnew <- DF |> mutate(across(everything(), as.character)) |> 
  pivot_longer(-Taxo) |> 
  pivot_wider(names_from = "Taxo", values_from = "value")

DFnew
#> # A tibble: 5 × 6
#>   name  T1    T2    T3    T4    T5   
#>   <chr> <chr> <chr> <chr> <chr> <chr>
#> 1 A     1     2     3     4     5    
#> 2 B     V     W     X     Y     Z    
#> 3 C     11    12    13    14    15   
#> 4 D     21    22    23    24    25   
#> 5 E     31    32    33    34    35
