401k direct rollover to Traditional IRA and Roth IRA. 1099r does not match IRA amounts

[Sigma24]

In 2021 rolled over my 401k with some after tax money and pretax money to a Roth IRA and a Traditional IRA.  This was a direct rollover  and the receiving custodian made all the arrangements for the  rollover.  After getting my 1099r from my 401k provider  I noticed that the IRA rollover amounts do not match what is on the 1099r.  There appears to be a miscommunication on the amount of  money that was to go to the Roth IRA.  I have followed up with the IRA custodian and they informed me they do not have any documentation related to the rollover and it was most likely handled by a phone call.  I need to report the additional amount of money that was moved to the Roth account and pay the taxes.  How do I do this.

You can enter a Substitute 1099-R to report the taxable distribution on your ROTH IRA conversion. You will see an option for this when you enter a form 1099-R in TurboTax on the screen that says Tell Us Which 1099-R You Have. Enter the same information you did for the form that reported the wrong amount, just adjust the amount to account for the additional taxable income.

So  am I creating a new 1099r that shows only the amount of the Roth conversion and nothing else with the Payer information from the receiving  Custodian.  Or are you suggesting changing the 401k  Administrators 1099r and adding the amount of the Roth conversion only to box 2a Taxable amount,  and leave all other entries the same.  I have also read that I will need to split the 1099r  into two separate 1099r forms, one for  the funds going to the Roth Ira and one going to the Traditional Ira.  Are you knowledgeable on this process as well?

Thanks for your help.

Make sure that you are not confusing your 401k contributions with your IRA conversion.

Anything that you contributed to your 401k will be on your W-2 from the employer and none of this will be listed on the 1099-R that is received from whoever you rolled the funds over to.  The 1099-R should have a code G designating it as a direct conversion rollover.  Download the IRS publication on IRA contributions, https://www.irs.gov/publications/p590b#en_US_2020_publink[phone number removed] and use the table and Chapter 2.  You may not have anything to report or correct.

I will create 1 substitute 1099r from the 401k administrator for the gross distribution of all the money that was direct converted to the new IRA (box 1).  I will remove the values in box 5 for the designated Roth contributions.  This will allow me  to answer all the question in the interview showing all the distribution went to a  Traditional IRA.  I will create a second substitute 1099 from the 401k administrator for the gross distribution of  the money that went to the new Roth IRA  (box 1).  I will add the taxable Roth conversion amount  in box 2a and include the designated Roth contributions in  Box 5.  This will allow me to answer all the interview questions showing the distribution went to a Roth IRA.    When these two 1099r are combined they should match up with the values in the original  1099r from the 401k administrator with the only exception being the taxable amount in box 2a.  Does this sound correct?  It looks like I will need to submit a form 4852 for the substitute 1099r.  Will I still be able to E-file or will the creation of the  form 4852 prevent this?  Thanks again for your help.

Yes, according to IRS.gov, "If the taxpayer is unable to secure and provide a correct Form W-2, W-2G, or 1099-R, the return may be electronically filed after Form 4852, Substitute for Form W-2, Wage and Tax Statement, or Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc. is completed in accordance with the use of that form".
